300 Win Mag vs 300 RUM

If I have a 300 Win Mag is there any reason for getting a 300 RUM? Would I gain enough over the Win Mag? I hunt mostly deer, but would like to use it for elk and moose if the opportunity presents itself.
Thanks.

I'll probably catch flak for this but I believe it is true. Probably more moose have been killed with a .270 or .30-06 than any other cartridge. My dad and I have killed 5 moose with .270's and only one took more than 3 steps. The last one was hit far back on a running shot, and was killed less than 100 yards away. I think an elk is a far tougher animal than a moose.

You have PLENTY, PLENTY, PLENTY of gun to hunt elk and moose with. I personally hunt with a 300 WSM now for everything because I wanted something I would feel comfortable with shots to 500 yards. Your 300 Win Mag has nearly identical ballistics (if not better) than the 300 WSM.

The reason I would potentially look at the 300 RUM is if I were putting together a long range rifle capable of doing the job at extreme ranges.

There are far better gun guys on this forum than I am, but I would say out to 500 yards you have all you need for moose and elk.

Umpqua, I couldnt agree more! The 300 RUM has a little better ballistics but you have to be shooting a looooooong ways for it to make much difference and it also comes with more recoil. If your happy with the 300 Win I would stick with it. If you are looking to get another gun I would look more toward the 300WSM or 325WSM because you can get them in lighter short action guns. If you really want a 300 RUM go for it! They are a good caliber.

Agree! My son has a .300 RUM that we reload for and the ballistics are only slightly better than my .300 Wby Mag.....and it takes 10 more grains of powder to get there. I personally don't think that using 10 grs more powder to gain 90 fps makes sense. It remains to be seen how his barrel life goes too.

Stick with your .300 Win Mag. If you don't reload, you should to get the most efficiency out of it.

I shoot a .300 Win Mag and hand load. I get great accuracy and long range effectiveness out of my rifle. I agree with others that you are gaining a little for a lot of money. Also if you ever do need a box of ammo in a pinch the .300 win mag is much more plentiful then .300 RUM. I would stick with what you have. You can kill anything in North America with a .300 win mag. UH is right, before my brother and I bought .300 win mags we shot elk and muleys with a .270 and 30.06. Good shot placement is more important then ultra mag power IMO.

Only plus side to the RUM is the ability to push the longer, higher BC bullets out of the tube a little faster. I have a cpl, several 300wm(s) and a boat anchor of a wsm that I've decided is about useless. I really don't see much difference between the 3 or had an animal tell any difference.
